fitting additional cigarette socket in fuse box
I've been trying to wire an extra cigarette socket directly through the fuse box, uising a piggy back fuse adapter and cigarette socket adapter.
I've blown two fuses in the sat nav charger cable and also the 20A mini fuse so far.
Not sure whats happening, but i've wired it this way. Split the cable from the cigarette adapter to reveal two wires, one wire is wired to the piggy back, and the other wire is wired wired to a earth/ground bolt near the fuse box. I've tested that power is coming through all the wires, but have blown three fuses so far.
There is a little led on the cigarette adapter but it doesnt light up, i'm assuming i have not found a decent ground/earth point?
Any advice as to where i am going wrong? Have i wired it incorrectly?
